testhyphens – Testing hyphenation patterns

The pack­age may be used for test­ing hy­phen­ation pat­terns or for con­trol­ling
that spe­cific words are hy­phen­ated as ex­pected. This pack­age im­ple­ments some
old TUGboat code to adapt it to LaTeX with some en­hance­ments.

It dif­fers form \showhy­phens, be­cause it type­sets its
out­put on the doc­u­ment’s out­put file. It also works with
xe­la­tex, where \showhy­phens re­quires a workaround.
